Question

in a two digit number the tens digit is three times the unit digit the if the digits are interchanged the new number formed is 36 less than the first number find the numbers ​

Answer 1

Step-by-step explanation:

HEY MATE ..

Let the one's digit be y and tens digit be x

,Number = 10x + y

Then,x=3y⋯(i)

Reversed number = 10y + x

A.t.Q :- (10x+y)−(10y+x)=36

Put x = 3y in eq. (i)⇒9x−9y=36⇒x−y=4⋯(ii)⇒3y−y=4∴2y=4 x=3y

∴x=6y=2

Let the one's digit be y and tens digit be x,

Number = 10x + y

Then,x=3y⋯(i)

Reversed number = 10y + x

A.t.Q :- (10x+y)−(10y+x)=36

Put x = 3y in eq. (i)⇒9x−9y=36⇒x−y=4⋯(ii)⇒3y−y=4∴2y=4 x=3y ∴x=6y=2∴

Number = 62
